Seminars organized by Eureca in cooperation with Caeleste

– Fundamentals on CCD and CMOS image sensors

Location: 2018/06/26 in Cologne, Maritim Hotel Köln, Heumarkt 20,

Contents: This seminar explains in detail the architecture and operation of CCD and CMOS image sensors and their resulting characteristics. The differences in architecture and physical limitations will be illustrated. Additionally, we will deal with measurement techniques for the characterisation of image sensors and the interpretation of specifications on data sheets.

  • development of bands in semiconductors
  • structure of photodiodes and pixels
  • charge transfer between single pixels
  • standard CCD sensors
  • full frame sensor, interline sensor
  • blooming, smearing
  • CMOS image sensors
  • noise sources (fixed pattern noise, read noise, KTC noise, 1/f noise, shot noise)
  • photon transfer
  • dynamics, signal-to-noise ratio, resolution

Costs: 399,- EUR (incl. taxes) per person including lunch, tea and coffee and training documentation. When booking before 2018/05/31 you can get a discount of 50 EUR.

Since the number of attendees is limited, please register as soon as possible via info@eureca.de. Your registration is only complete, when you receive a confirmation E-mail and the invoice is paid.

– Free information event about replacements for obsolete ILX sensors

Location: 2018/06/27 in Cologne, Maritim Hotel Köln, Heumarkt 20, 10 AM – 5 PM

On the 27th of June 2018 we organize a free information event about CCD linear sensors in Cologne. First, we talk about the comparison of data sheet specifications from different manufacturers. Afterwards, in cooperation with our partner Caeleste, we present possible replacement solutions for the discontinued Sony linear sensors of the ILX series.

When selecting optical sensors for a special application, technical specifications of different sensors have to be compared.  Unfortunately, the information in sensor data sheets are often not direct comparable because the manufacturers use different measuring methods and parameters. Even seemingly unambiguous information, such as the spectral sensitivity, lead regularly to misinterpretations, as many manufacturers do not specify the used units and choose them in a way that the curves appear optimal. A direct comparison is thus not possible.

This seminar is first about to find a universally valid and comparable parameter set for the description of the properties of image sensors.
Subsequently, it is shown as an example, how to extract or estimate these parameters from data sheets. For cases where image systems already exist, a simple method for measuring essential parameters is explained.

In addition to this general information we will discuss the universally valid parameters for some of the obsolete line sensors of the ILX series by Sony and the possibilities of a replacement.

Free seminar but since the number of attendees is limited, please register as soon as possible via info@eureca.de. Your registration is only complete, when you receive a confirmation E-mail and the invoice is paid.

 Caeleste at the Sound of Science on May 27th

On Sunday May 27th Caeleste participated in the first edition of “Sound of Science”, a STEM promotion event. We brought two demos to the event and both attracted a lot of attention from the public. Our Wireless Personal Radiation Detection device (WPRD) was developed as part of a Eurostars project together with our Korean partner FC Unwired. The device can demonstrate the natural radiation of e.g. …. bananas! We also demonstrated our capability to read through closed envelopes. This demo was particularly enjoyed by our younger visitors!

Of course we also promoted the 2018 edition of the Electroniad and held a mini-quiz at our booth. It triggered a lot of interest and many people tested their technical skills and knowledge in this unusual setting.  www.electroniad.org

The Caeleste team had a fun day at the Sound of Science and our visitors too!


The winning team of Caeleste’s 2018 Foosball Competition

In general, “foosball” (table football) is mainly a sport that people play for fun in a smoky bar, but we play it at the office!

The game still doesn’t even have a single set of rules – or one name. You’ve got langirt in Turkey, sjotterkas in Belgium,  jouer au baby-foot in France, csocso in Hungary, cadureguel-schulchan in Israel, plain old table football in the UK, and a world encyclopedia of ridiculous names elsewhere around the globe. The American “foosball” (where a player is called a “fooser”) borrowed its name from the German  “fußball” (Read more: “The murky history of Foosball”)

Congratulations to our ‘foosers’ who won the 2018 Caeleste Foosball Competition!


Caeleste Career Day

The 2018 edition of the Caeleste Career Day was a big success. We met a group of enthusiastic and talented students eager to develop their potential working in a dynamic and innovative environment where dealing with cutting-edge technology is a daily routine. Thanks to our visitors for stopping by and for your interest in Caeleste!
